Application filed June 16, 1915. Serial No. 34,503.

T 0 all whom it may concern Be it known that I, Ranroxo Ivax GRAF, acitizen of the United of America, residing at Grand Rapids, inthe-county of Kent and State of Michigan, have invented certain new anduseful Improvements in Methods of Assembling and Securing TogetherSeparated Parts; and I do hereby declare the following to be a full,clear, and exact description of. the invention, such as will enableothers skilled in the art to which it appertain's to make and use thesame.

This invention relates to a method of assembling and securing togetherelements to make complete articles of hardware.

It is the object and purpose of the invention to provide efficient meansfor assembling the different parts of hardware structures which can bereadily and easily 'performed and which is very economical in cost ofmanufacture.

The application of this method and means to various articles is shown inthe acc om panying drawing, in which:

Figure 1 is a side elevation with parts shown in section illustratingthe assembly of a door butter and the attaching screw therefor, an endelevation of the device also being shown in the figure. Fig. 2 is asimilar view of the screw and the connecting disk which is used toconnect it with the body of the door bull'er. Figs. 3 and .4. are viewssimilar to Figs. 1 and 2 showing the use of my invention in attaching adoor.

knob to the latch operating rod.

Like reference characters reter to like parts throughout. the severalviews of the I drawing.

In the assembly of the door buffer and attaching screw the body 1 has atone end the usual bufi'er head 2 and at the opposite end is of greaterdiameter and formed with a base 1 in which a depression 3 is out havinginclined sides 4. A smaller depression 5 is cut in the body 1 and ispositioned substantially centrally of the larger depression 3. Thedepression 5 may be of any suitable conformation.

An attaching screw 6 adjacent its end is provided with a collar 7 and'irojecting at right angles from the collar is a stud or projcction 8adapted to seat in the depression 5.

A dome-like disk 9 having a central opening to receive the shank of-thescrew 6 passes over the screw and bears against the collar 7 this diskbeing of a diameter such that its outer edges will be barely receivedwithin the outside opening of the depression 3. The screw and disk areseated within the depression 3 with the projection 8 within thedepression 5 and the disk is then subjected to pressure or otherwiseoperated upon so that it is flattened, the outer edges of the diskcoming into contact with the inclined sides 4 of the depression 3 asshown. In this manner a very firm and substantial connection of theattaching screw to the body 1 of the butter is effected and one whichcannot be broken except by distortion of the connecting disk 3. Therectangular shape of the projection 8 and of the depression 5 receivingit is for the purpose of causing the screw to always turn with the bodyand any shape of projection and depression that will afford this is allthat is necessary.

In Figsv 3 and 4 the door knob 1 is connected to the rod 6 in the samemanner that the body 1 is connected to the screw 6 as heretoforedescribed, the depression 3 having inclined sides 4 with a centralirregular depression 5" adapted to receive the projecsimilar in everytion 8 of the rod 6 being respect to depressions 3 and 5 elined sidesat. to depression 3 in the predescribcd structure. The disk 9 seats inthe depression 3 and engages against the collar 7 in identically thesame manner and secures the knob to the rod "the same Way. The onlymodification required is that the cen tral openingin the disk 9 be of ashape to pass over the rod.

Various other modifications and ways of the various parts or elements ofarticles of hardware will occur to others skilled in the art. Theinvention accordingly is not limited to the disclosures made but coversall modifications within the scope of the append claim which defines theinvention.

I claim The method of assembling and connectusing this method and meansof assembling ing separated parts which consists in providing two partsto be connected together one of said parts having a depression with withthe ininclined sides therein, inserting the other part partially intosaid depression, then I passing a securing disk of dome-like formationover said other part and into thede- 5 pression, and then flattening thedisk to force its edges against the inclined sides of the depression.substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.
